An energy storage type of dual-drive coupled power distribution system adapted to an all wheel driving (AWD) transportation means having a revolution output end from an internal combustion engine that drives front-end load through a front-end transmission by means of an intermediate transmission providing gear-changing or clutching function and a control interface or coupling device; and to couple to revolution input end of a dual-drive type of electromagnetic coupling device, further to drive rear-end load through the other revolution output end of the dual-drive type of electromagnetic coupling drive device made in the construction of a revolving dual-end shaft with both end shafts respectively incorporated to a revolving magnetic filed structure and a revolving rotor structure to regulate the power distribution between the front-end and the rear-end loads while being subject to the manipulation by a control device.
